Timeslot Node Buttons

Click to open a window with a list of pre-defined timeslot configurations for Advanced GSM/EDGE/EGPRS2-A, Half Rate GSM/EDGE/EGPRS2-A, Advanced EGPRS2-B carriers, or Control Carrier. To replace the current configuration in the Timeslot node with one of these pre-defined configurations, select the desired configuration and click OK or double-click the desired configuration.

The Advanced GSM/EDGE/EGPRS2-A, Advanced EGPRS2-B carriers, Advanced EGPRS2-B, and Advanced Control carriers require Option QFP.

Click to open a drop down menu from which you can:

Timeslot Parameters

Select a timeslot from the list at the top of the window. The parameters that you configure at the bottom of the window apply to the selected timeslot.

Timeslot Number

Displays the number of the selected timeslot. The parameters you set apply to this timeslot.

State

Choice: On | Off

Default: On

Double-click or use the drop-down menu to set the state of the timeslot On or Off.

Power

Range: –70 to 0 dB.

Default: 0 dB

Enter a value to set the timeslot power.

Channel Type

This cell requires Option QFP and the selection of one of the ClosedAdvanced carriers. Double-click or use the drop-down menu to select the channel type, which is dependent upon the selected advanced carrier:

Advanced GSM/EDGE/EGPRS2-A Carrier

Choice: Coded TCH/FS | Coded TCH/WFS 12.25k | Coded TCH/WFS 8.85k | Coded TCH/WFS 6.60k | Coded CS-1 | Coded CS-4 | Coded Downlink MCS-1 | Coded Uplink MCS-1 | Coded Downlink MCS-5 | Coded Uplink MCS-5 | Coded Downlink MCS-6 | Coded Uplink MCS-6 | Coded Downlink MCS-7 | Coded Uplink MCS-7 | Coded Downlink MCS-8 | Coded Uplink MCS-8 | Coded Downlink MCS-9 | Coded Uplink MCS-9 | Coded E-TCH/F43.2 | Coded UAS-11 | Normal GMSK Burst | Normal 8PSK Burst | Normal 16QAM Burst | Normal 32QAM Burst

Default: Coded TCH/FS

Advanced EGPRS2-B Carrier

Choice: Coded UBS-6 | Coded UBS-8 | Coded UBS-11 | HSR QPSK Burst | HSR 16QAM Burst | HSR 32QAM Burst

Default: Coded UBS-6

Control Channels

Choice: FCCH+SCH+BCH+CCCH | FCCH+SCH+BCCH+CCCH+SDCCH/4(0…3)+SACCH/C4(0…3)

Default: FCCH+SCH+BCH+CCCH

When Standard Combined BCH Channel is selected, the contents are different for different frames in a multiframe. The reason is that different bursts (FCCH, SCH, BCCH, SDCCH, SACCH and CCCH) are time multiplexed together for BCH channel according to the standards. But, if the channel type is not Standard Combined BCH Channel, every timeslot on frames has same timeslot configuration type.

The default channel type is different for different timeslots. For timeslot 0, the channel type is Standard Combined BCH Channel. For all the other timeslots, the default channel types are Dummy Burst.

The default channel types for different timeslots follow the 3gpp standards. But, other channel types are provided to enable greater measurement flexibility. The channel types used in the Control Channel, don’t contain any coded TCH or coded PDTCH type, to avoid excessive traffic channel information on Control Channel. If it is desired to mix BCH and TCH/PDTCH together, use multi-carriers. ClosedExample:Control Channels as BCH, and Advanced2-A as TCH or PDTCH.

Modulation

Displays the modulation type (appropriate to GSM/EDGE/EGPRS2). This setting is not editable.

Regardless of the Channel Type, when using Control Channels, always use GMSK as the modulate type for the Control Channel.

Multislot

Choice: On | Off

Default: Off

Double-click the cell or use the drop-down menu to set the multislot state On or Off . When multislot is on, the power level is maintained between timeslots.
